Go to: Dark Age of Camelot Downloads, and choose the first option for the full game client.
Install it, if you already have a DAoC Client copy it to a new directory, you wont be able to play on live server with this client again!
If you play on Uthgard, you need to have another Client aswell, their Client isn't compatible with Instant50

Instant50 can be best played using our Launcher, you can download it here.
The Launcher will keep your Client updated so that you are able to play on Instant50.
